[TYPO3-core] RFC: #847: error in tslib_fe->getFromCache()

Hi,

Are you sure? Normally what you get in such cases is a warning that the 
variable is not initialised. This why isset() is useful. Obviously this 
depends on the level of error reporting of your local PHP install, but 
it's cleaner to test if a variable is set before testing  it.

Cheers
